Description

【０００１】
【発明の属する技術分野】
本発明はデスク、カウンタ、テーブルそしてパネルの如き家具等にあって、既知の如く床面等から引き出した配線を、パソコンなどに接続する際、当該配線をデスク等の天板とか側板などに配線挿通用孔を予め開口しておくことで、当該配線挿通用孔にコード等を挿通しないときにあっても外観上の体裁を損なわないようにすると共に、使い勝手をもよくするため、上記配線挿通用孔に予め嵌合しておくようにした係嵌キャップに関する。
【０００２】
【従来の技術】
【特許文献１】実開平７−２４１３５
【０００３】
既にこの種の配線挿通用係嵌キャップは多用されており、図５がその市販品の一例であって、予めデスクの天板Ａに穿設しておいた配線挿通孔Ｂに、係嵌キャップａの小径嵌合筒ｂを上方から係嵌することで、その抜け止め周縁蓋部ｃが天板Ａ上に係当するようにし、このことで当該装填状態を保持するようにしている。この際図５（Ｂ）により理解される通り上記抜け止め周縁蓋部ｃには、配線用挿通口ｄが開口されており、ここで図５（Ａ）のｅは抜止用突周条を示している。
しかしこのような配線挿通用係嵌キャップは、単に天板Ａにおける配線挿通孔Ｂ嵌め落としてあるだけであるため、これをデスクなどの側板とかパネルに採択した場合には、当然のことながら振動その他の外力などを受けることで不本意に外れ落ちてしまう欠陥がある。
【０００４】
そこで側板に配線挿通用係嵌キャップを取着するためのものとしては図６により示されている通り（特許文献１参照）、ダクトｆを机ｃの内方に入れ、ダクトｆの各端部を側板ｇに穿設の配線孔ｈに整合するように支持し、その状態でまず一方の側板ｇの配線孔ｈから配線枠ｉの取付枠部分ｊをダクトｆの端部に嵌合するまで挿入し、次に他方の側板ｋにあっても同上作業をすればダクトｆを机Ｃに取り付けられるというものである。
従って上記公知例によるときは確かに側板ｇに取り付けても、配線枠ｉが抜け落ちることはないが、配線は一方の配線枠ｉから他方の配線枠までダクトｆ中を挿通させなければならないことから、自由度が制約されて使い勝手が悪いこととなる。
【０００５】
【発明が解決しようとする課題】
本発明は上記のような従来の配線挿通用係嵌キャップが有する欠陥に鑑み検討することにより、天板はもちろんのこと、縦板にあっても支障なく採択できるようにしたもので、請求項１によるときは一対の第１、第２筒状体を板体の配線挿通孔に嵌装してやることで、当該板体の板厚に合わせて挟持自在なるよう取着可能とし、さらに当該第１、第２筒状体の外側から一対の第１、第２蓋体を係脱自在に係止可能なるよう構成するのである。
かくして板厚寸法の大小を問わず、第１、第２筒状体を抜出の心配なしに取着して、これまでのように天板でなく側板に装填しても抜け落ちることのないようにし、さらに第１、第２蓋体によって外観を美麗に保持し得ると共に、通常は第１、第２蓋体に開設してある少量配線用通口を利用し得ることになるが、さらに多量の配線を挿通したいときには、同上第１、第２蓋体を第１、第２筒状体から離脱してしまうことで、当該第１、第２筒状体に大きく開通されることになる多量配線用通口を活用し得るようにするのが、その目的である。
【０００６】
さらに請求項２ないし請求項４は、何れも請求項１の実施態様項であるが、請求項２にあっては、板体と少なくとも一方の筒状体との間にスペーサを挟入することで、挟持状態の強化を図り得るようにし、さらに請求項３では板体の板厚に合わせて挟持自在とした一対の第１、第２筒状体相互の係止手段として、第１、第２歯合部を適所に設けることによって、上記板厚が変化しても挟持状態を確保し得るようにしている。
また請求項４にあっても、第１、第２筒状体と第１、第２蓋体との係嵌状態が不本意に抜出してしまうことを阻止するための抜止手段として、第１、第２筒状体と第１、第２抜け止め内側段差部と、第１、第２蓋体の第１、第２蓋突部とが係脱自在に係合するようにしたり、第１、第２筒状体と第１、第２抜け止め軸線側圧接部に対し、第２蓋体の第１、第２抜け止め反軸線側圧接部が弾接して、これによる充分な摩擦抵抗力を発揮可能とすることで、第１、第２蓋体の不本意な離脱を、より確実に阻止しようとしている。
【０００７】
【課題を解決するための手段】
本発明は、上記の目的を達成するため板体に貫設された配線挿通孔には、対向状態にて配線挿通孔における外周側に嵌入することにより、板体の板厚に合わせて挟持自在とした係止手段を備えた一対の第１、第２筒状体と、当該第１、第２筒状体に向けて挿入内嵌した第１、第２蓋体が、夫々上記の第１、第２筒状体に対して抜け止め状態で係嵌自在に係止される抜止手段を備えていると共に、当該第１、第２蓋体には夫々第１、第２少量配線用通口が穿設され、この第１、第２蓋体を夫々前記第１、第２筒状体から離脱することで、当該第１、第２筒状体により開通された多量配線用通口の開通状態が形成されるようにしたことを特徴とする配線挿通孔用係嵌キャップを提供しようとしている。
【０００８】
そして請求項２ないし請求項４は何れも請求項１に従属する請求項であり、請求項２であれば板体に貫設された配線挿通孔には、対向状態にて配線挿通孔の外周側に嵌入することにより、板体の板厚に合わせて挟持自在とした一対の第１、第２筒状体が設けられ、さらに当該板体と少なくとも一方の筒状体との間にスペーサを挟入することで、当該挟持状態の強化を可能としている。
【０００９】
そして請求項３の場合であると板体に貫設された配線挿通孔には、対向状態にて配線挿通孔における外周側に嵌入することにより、板体の板厚に合わせて挟持自在とした一対の第１、第２筒状体相互の係止手段としては、第１、第２筒状体の軸線方向へ所定ピッチで形成した第１、第２歯合部が、全周または所要複数箇所にあって係脱自在に設けられていることを、その内容としている。
【００１０】
さらに請求項４の実施態様によると、板体に貫設された配線挿通孔には、対向状態にて配線挿通孔における外周側に嵌入することにより、板体の板厚に合わせて挟持自在とした一対の第１、第２筒状体と、当該第１、第２筒状体に向けて押入内嵌した第１、第２蓋体が、夫々上記の第１、第２筒状体に対して抜け止め状態で係嵌自在に係止される抜止手段が、上記第１、第２筒状体に形成の第１、第２抜け止め内側段差部に対して、前記の第１、第２蓋体に形成した第１、第２蓋突部を係脱自在なるよう係嵌して、第１、第２蓋体の離脱を阻止するか、同上抜止手段が第１、第２筒状体に形成の第１、第２抜け止め軸線側圧接部に対して、第１、第２蓋体に形成した第１、第２抜け止め反軸線側圧接部が弾接して、第１、第２蓋体の離脱を阻止するようにしたことを、その内容としている。
【発明の実施の形態】
【００１１】
本発明の要旨につき図１ないし図４を参照して以下説明すると、請求項１にあって不可欠とする部材は一対の第１、第２筒状体１Ａ、１Ｂと、これまた一対の第１、第２蓋体２Ａ、２Ｂとであり、前掲第１、第２筒状体１Ａ、１Ｂには、机の側板等である板体Ｙの板厚Ｄに合わせて挟持自在とした係止手段１Ｃが備えられていると共に、後掲第１、第２蓋体２Ａ、２Ｂには、これを上記の第１、第２筒状体１Ａ、１Ｂに向けて押入内嵌することで、第１、第２筒状体１Ａ、１Ｂに対して抜け止め状態で係嵌自在なるよう係止される抜止手段３が具備されているのであり、図中Ｈは上記した板体Ｙに貫設された配線挿通孔を示している。
そして、さらに第１、第２蓋体２Ａ、２Ｂには第１、第２少量配線用通口２ａ、２ｂが穿設されており、従ってこの状態では少量の配線を嵌装処理することができることになるのに対し、この第１、第２蓋体２Ａ、２Ｂを夫々第１、第２筒状体１Ａ、１Ｂから離脱してしまえば、第１、第２筒状体１Ａ、１Ｂにより開通されることになる多量配線用通口４の開通状態が得られることになるのである。
【００１２】
ここで、図面に開示された具体例によって、さらに請求項１に係る発明の内容を理解し易くすると、まず第１、第２筒状体１Ａ、１Ｂは図１（Ｂ）（Ｃ）、図２そして図４を参照して理解できる通り、配線嵌装孔Ｈへの嵌入使用に際して、板体Ｙの各面に夫々押当される第１、第２周縁部１ａ、１ｂと、これよりも小径の第１、第２環状部１ｃ、１ｄを具備しており、図中この第１環状部１ｃにおける第１周縁部１ａ寄りにあって、所定離間距離だけ突出したのが第１筒状体１Ａの不本意な回動を阻止するための回止用小突起１ｅを示している。
【００１３】
さらに前掲係止手段１ｃとしては、各種のものが技術的に想定可能であるが、図示例では第１環状部１ｃを先端へ向けて縮径状態に形成しておき、その自由端部内側には第１噛合部１ｆを、周方向へ鋸歯状にて少数箇形成しておき、これと係合するように形成した第２筒状体１Ｂにおける第２環状体１ｄの外側には、可成りの長さにわたり第２噛合部１ｇを形成する。この際図示例では山型歯状に形成してあり、この結果第１、第２筒状体１Ａ、１Ｂを図示の如く板体Ｙ内へ嵌入すれば板厚Ｄに可成り大小の差異があったとしても、板体Ｙは第１、第２周縁部１ａ、１ｂによって挟着状態に保持することができる。（請求項３）。
そしてこの際、上記の挟着強度に不満を生じた場合には、図１（Ｂ）により開示の如く板体Ｙと第２周縁部１ｂとの間に適宜厚さのスペーサ５を挟入することで、上記の不満を解消することが可能となる。（請求項２）。
【００１４】
さて、本発明では上記のようにして装填し終った第１、第２筒状体１Ａ、１Ｂに対して図面上、左右から第１、第２蓋体２Ａ、２Ｂを押入嵌合させることになるが、これは嵌合後にあって不本意な離脱が生ずることを阻止しなければならないことから、前掲抜止手段３としての第１、第２の実施態様（請求項４）について、夫々図１（Ｃ）と図２を参照して以下夫々につき説示する。
すなわち抜止手段３の上記第１実施態様にあっては、第１、第２筒状体１Ａ、１Ｂに形成された第１、第２抜け止め内側段差部１ｈ、１ｉに対して、前記の第１、第２蓋体２Ａ、２Ｂに形成した第１、第２蓋突部２ｃ、２ｄ（断面半円状）を係脱自在なるよう係嵌することで、第１、第２蓋体２Ａ、２Ｂの不本意な外方への離脱を阻止するのである。
そして同上第２実施態様にあっては、当該抜止手段３なるものを、第１、第２筒状体１Ａ、１Ｂの第１、第２抜け止め軸線側圧接部１ｊ、１ｋに対して、第１、第２蓋体２Ａ、２Ｂに形成した第１、第２抜け止め反軸線側圧接部２ｃ、２ｄが弾接状態となるようにし、この弾接に基づく摩擦抵抗によって第１、第２蓋体２Ａ、２Ｂの不本意な離脱を阻止しようとしている。
【００１５】
【発明の効果】
本発明は請求項１に明示されている通り、まず一対の第１、第２筒状体を板体の配線挿通孔に嵌装することで、各種寸法の板厚である板体に対して挟着自在なるよう取着でき、さらに第１、第２筒状体の外側から内側へ向けて一対の第１、第２蓋体を係脱自在なるよう係止できるので、第１、第２蓋体が表出されて外観も美麗に仕上げることができるのはもちろん、天板でなく、側板に取り付けても不本意に抜け落ちてしまう心配を皆無とすることが可能となる。
しかも通常は第１、第２蓋体の第１、第２少量配線用通口を利用できるのはもちろん、多量の配線を処理したいときには、第１、第２蓋体を強制的に抜き去ってしまえば、第１、第２筒状体により大きく開通されることとなる多量配線用通口を活用できることになる。
【００１６】
そして何れも上記請求項１の実施態様を示す他の請求項については、請求項２の場合であれば、スペーサを適所に活用することで板体に対する第１、第２筒状体の板厚に合わせての挟持状態を、がたつきのないより強力なものとすることができる。
そして請求項３によるときは、第１、第２筒状体相互の係止手段として、第１、第２噛合部を適所に設けることで、板厚が可成り変化しても挟持状態の確保を保証し得ることになる。
さらに請求項４によれば、第１、第２筒状体と第１、第２蓋体との抜け止めのための手段として、第１、第２筒状体の第１、第２抜け止め内側段差部と、第１、第２蓋体の第１、第２蓋突部とが係合するようにしたり、さらには第１、第２抜け止め反軸線側圧接部に対して、第２蓋体の第１、第２抜け止め反軸線側圧接部が弾接して第１、第２蓋体の不本意な離脱につき、その阻止力に関し信頼性を向上することが可能となる。

[Prior art]
[Patent Document 1] Japanese Utility Model Laid-Open No. 7-24135
[0003]
FIG. 5 shows an example of such a commercially available product, in which a wire insertion hole B previously formed in a top plate A of a desk is inserted into a wire insertion hole B. FIG. By engaging the small-diameter fitting cylinder b of a from above, the retaining peripheral lid c is engaged with the top plate A, and the loaded state is maintained. At this time, as is understood from FIG. 5B, a wiring insertion hole d is opened in the retaining edge cover c, where e in FIG. 5A indicates a retaining ridge. ing.
However, since such a wire insertion engaging cap is merely fitted into the wire insertion hole B in the top plate A, if this is adopted for a side plate such as a desk or a panel, it naturally causes vibration. There is a defect that unintentionally falls off by receiving other external force.
[0004]
Therefore, as shown in FIG. 6 (see Patent Document 1), the duct f is inserted into the inside of the desk c, and each end of the duct f is attached as shown in FIG. Is supported on the side plate g so as to be aligned with the wiring hole h formed in the side plate g. In this state, the mounting frame portion j of the wiring frame i is first fitted from the wiring hole h of one side plate g to the end of the duct f. The duct f can be attached to the desk C by inserting it and then performing the same operation on the other side plate k.
Therefore, according to the above-mentioned known example, although the wiring frame i does not fall out even if it is attached to the side plate g, the wiring must be inserted through the duct f from one wiring frame i to the other wiring frame. However, the degree of freedom is restricted and the usability is poor.
[0005]
[Problems to be solved by the invention]
The present invention has been made in consideration of the above-mentioned defects of the conventional wire insertion engaging cap, and has been made so that it can be adopted without any problem even in the vertical plate as well as the top plate. In the case of (1), a pair of first and second cylindrical bodies are fitted into the wiring insertion holes of the plate so that the first and second cylindrical bodies can be attached so as to be able to be pinched according to the thickness of the plate. The pair of first and second lids are configured to be able to be detachably locked from the outside of the second cylindrical body.
Thus, regardless of the size of the plate thickness, the first and second cylindrical bodies can be attached without worrying about pulling out, so that they will not fall off even if they are loaded on the side plate instead of the top plate as before. In addition, the appearance can be beautifully maintained by the first and second lids, and a small amount of wiring opening usually provided in the first and second lids can be used. When it is desired to insert the wiring, the first and second lids are separated from the first and second cylindrical bodies in the same manner as described above, so that the first and second cylindrical bodies are largely opened. The purpose is to make use of the wiring openings.
[0006]
Further, any of claims 2 to 4 is an embodiment of claim 1, but in claim 2, a spacer is inserted between the plate and at least one cylindrical body. Thus, the holding state can be strengthened, and in the third aspect, first and second locking means for the pair of the first and second cylindrical bodies that can be freely held according to the thickness of the plate body are provided. By providing the two meshing portions in place, it is possible to secure the sandwiching state even if the plate thickness changes.
Also, in the present invention, the first and second tubular members are provided as first and second stoppers for preventing the engaged state of the first and second lids from being unintentionally withdrawn. The second cylindrical body, the first and second retaining inner step portions, and the first and second lid projections of the first and second lids are engaged with each other in a detachable manner. The first and second retaining anti-axis side pressure contact portions of the second lid body elastically contact the second cylindrical body and the first and second retaining axis side pressure contact portions, thereby providing a sufficient frictional resistance. By making it possible to exert, it is intended to more securely prevent the first and second lids from being unintentionally detached.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is configured such that a wire insertion hole penetrated through a plate body is inserted into an outer peripheral side of the wire insertion hole in a facing state so that the wire can be pinched according to the thickness of the plate body.

The first and second lids are provided with first and second small-sized wiring passages, respectively. The first and second lids are detached from the first and second cylindrical bodies, respectively, thereby opening the large-volume wiring opening opened by the first and second cylindrical bodies. It is intended to provide an engagement cap for a wiring insertion hole, characterized in that a state is formed.
[0008]
Claims 2 to 4 are all dependent on claim 1. In the case of claim 2, the outer periphery of the wire insertion hole is opposed to the wire insertion hole provided through the plate body. A pair of first and second cylindrical bodies are provided so as to be pinched according to the thickness of the plate body by being fitted into the side, and a spacer is provided between the plate body and at least one of the cylindrical bodies. By sandwiching, the holding state can be strengthened.
[0009]
In the case of the third aspect, by fitting into the outer peripheral side of the wiring insertion hole in a facing state, the wiring insertion hole penetrated through the plate body can be pinched freely according to the thickness of the plate body. The first and second engaging portions formed at a predetermined pitch in the axial direction of the first and second cylindrical bodies may be the entire circumference or a plurality of required portions. The content is that it is provided at a location and is freely detachable.
[0010]
Further, according to the embodiment of the present invention, by fitting into the outer peripheral side of the wiring insertion hole in a facing state in the wiring insertion hole penetrating through the plate, it is possible to pinch according to the thickness of the plate. The pair of first and second cylindrical bodies and the first and second lids which are pushed and fitted into the first and second cylindrical bodies are respectively attached to the first and second cylindrical bodies. On the other hand, a retaining means, which is engaged with the retaining member so as to be freely engaged with the retaining member, is provided on the first and second retaining inner step portions formed on the first and second cylindrical bodies. The first and second lid projections formed on the two lids are engaged so as to be detachable, so that the first and second lids are prevented from coming off, or the retaining means is provided with the first and second cylindrical members. The first and second retaining anti-axis side pressure contact portions formed on the first and second lids resiliently contact the first and second retaining axis side pressure contact portions formed on the body, and the first and second retaining stopper axial contact portions are formed on the first and second lids. Prevent detachment of two lids That in the way that has been and its contents.

【The invention's effect】
According to the present invention, a pair of first and second cylindrical bodies are first fitted into wiring insertion holes of the plate body to make the plate body of various sizes have a thickness. The first and second lids can be engaged so that they can be freely attached and detached, and the pair of first and second lids can be detachably engaged from outside to inside of the first and second cylindrical bodies. Not only can the lid be exposed and the appearance can be beautifully finished, but also there is no need to worry about unintentionally falling off even if it is attached to the side plate instead of the top plate.
In addition, usually, the first and second small-sized wiring openings of the first and second lids can be used, and when a large amount of wiring is to be processed, the first and second lids are forcibly pulled out. Once this is done, it is possible to utilize a large amount of wiring openings that are largely opened by the first and second cylindrical bodies.
[0016]
In the case of claim 2, the thickness of the first and second cylindrical members with respect to the plate member is determined by utilizing the spacer in an appropriate position. Can be made stronger without rattling.
According to the third aspect of the present invention, the first and second meshing portions are provided at appropriate positions as means for locking the first and second cylindrical bodies, so that the holding state is ensured even when the plate thickness changes considerably. Can be guaranteed.
Further, according to the present invention, the first and second stoppers of the first and second tubular bodies are provided as means for preventing the first and second tubular bodies from falling off from the first and second lids. The inner step and the first and second lid protrusions of the first and second lids are engaged with each other. It is possible to improve the reliability of the first and second stoppers against the unintended detachment of the first and second lids by the first and second retaining anti-axis side pressure contact portions being elastically contacted with each other.
